Granted: 1995-07-20
Abstract: Polyester having more than 1.0 of an inherent viscosity was spun and wound in the low speed of 600 m/min. In this step an undrawn yarn was directly drawn. The undrawn yarn was drawn with a high temperature steam at 480-550 degree C on the third step, and relaxed to give the high tenacity polyester fiber. Thus, a polyester chip (inherent viscosity 1.02) was spun at 305 degree C through a nozzle (diameter 0.42 mm, 196 holes), and cooled to 15 degree C, 0.5 m/min air. The yarn was wound in the speed of 500 m/min after oiling.

Patent KR-0163442-B1 (KR)
Title: Opening device for a packaging container and method of manufacturing the same
Inventor: NEDSTEDT ULF
IPC: B65D41/04
Filed: 1992-03-27
Granted: 1998-12-01
Abstract: The closure part (3) of the opening device (2) engages form-lockingly with, and encloses the end of the pouring spout (21, 33) facing away from the packaging container. This end consists of a connected, liquid tight layer of material which is shaped according to the internal shape of the closure part (3). The liquid tight layer of material, can only be penetrated in connection with the opening of the opening device. The spout is formed with the closure part (3) used as a mould with heated thermoplastics material layer forced into the closure part through a pressure difference.

Title: Automatic opening and shutting device for door
Inventor: HO CHANG-IN
IPC: E05F15/04
Filed: 1992-05-28
Granted: 1995-07-14
Abstract: a pressure accumulator (3) for removing pressure pulsations generated in the pressurised oil outputted from the oil-hydraulic pump; a pressure control valve (10) for controlling a flow direction of the pressurised oil applied from the oil-hydraulic pump to it; a controller (8) for controlling the pressure control valve in response to input signals; an intermittent gearing assembly (20) for transmitting rotational motion caused by the pressurised oil acting on it to the door to automatically open or close the door; a hydraulic rotator (30) for converting the hydraulic power of the pressurised oil into rotational motion of the intermittent gearing assembly; and a lock bar (36) for locking the door.

Title: Wax pasting apparatus fo rearface polishing of semiconductor device
Inventor: LEE JAE-HO
IPC: H01L21/30
Filed: 1992-06-16
Granted: 1995-10-06
Abstract: The device comprises; a vacuum chuck which adsorbs the back side of a semiconductor wafer by the vacuum; a supporting substrate which supports the glass substrate by making the region of glass substrate which a wax layer is formulated sticks to the front side of the semiconductor wafer by the wax layer and in addition, the front side of semiconductor wafer is exposed and the semiconductor wafer have the hole implanted and is equipped to the vacuum chuck.
Patent KR-960005726-B1 (KR)
Title: Device for supplying paper used in paper cup manufacture machine
Inventor: KIM CHANG-SUK
IPC: B31B1/60
Filed: 1992-08-18
Granted: 1996-05-01
Abstract: The device supplies a side paper to a paper manufacturing machine by supplying power to shafts(4a-4f) using gears(5a-5d). Rotation of the first shaft(4a) of a main shaft is transferred to the third shaft(4c) installed vertically via the second shaft(4b). A gear(5a) installed on the third shaft(4c) is connected with a decelerating gear(5b) of the forth gear(4d). A semi-gear(5c) on decelerating gear(5b) of the forth shaft(4d) is connected with a pulley(6a) of the fifth shaft(4e). A side cap(7) is installed below decelerating gear(5b) to up or down a working rod(20) using a roller(23) which is installed at the back of the working rod(20). The sixth shaft(4f) having a plate(8) and a pulley(6b) is installed on end parts of the working rod(20) and a supporting rod(24) respectively. The power is transmitted to the forth shaft(4d) periodically using a belt(10) and pulleys(6a),(6b) in between the fifth shaft(4e) and the sixth shaft(4f). A connecting rotation plate(26) is installed on the other side of the pressing plate(8).
